[RE-wrenches] Dial torque wrench for S-5 Clamps

I’ve been liking the Proto torque wrench <https://www.zoro.com/proto-dial-torque-wrench-drive-size-38-in-j6177f/i/G1663663/?q=G1663663> I purchased from Zoro a couple years back. I often wrap the head in masking tape to protect the roofing finish when torquing S-5 clamps due to the limited distance you end up with to the finish roof material  especially if the standing seam is tilted at an acute angle on set screw side. I use the same wrench for the Ironridge clamps. Also, surely you’re specific to which clamp you’re selecting but there’s definitely a few clamps that are more universal than others and when the roof profile allows I always select the S-5-N over some of the others. That little return profile hook is key to a successful bite without trying to walk up as it tightens. I see it has also been improved again with an angled set screw to eliminate the tilted seam headache I spoke about above. Bonus!
